IMPROVEMENT IN LOCK-COCKS.

Specification forniiu g part of Letters Patent No. 125,799, dated April16, 1872.

To all whom it may concern:

Be it known that I, HENRY ESSEX, of M eadville, in the county ofCrawford and State of Pennsylvania, have invented certain new and usefulImprovements in Lock-(locks; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawing and to the letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in one or more holes in the plug,with a hole in the body, so that the plug may be looked either open orshut by means of a pin, and a staple in the body over said pin for theattachment of a padlock, so that the pin cannot be raised to unlock theplug without first removing the padlock.

In order to enable others skilled in the art to which my inventionappertains to make and A represents the body of the cock, and B r theplug of the same. In the body A is ahole for the passage of a pin, a,and in the-plug B are two or more holes corresponding with the hole inthe body, so that the pin a may drop into the same and lock the plugeither open or shut, as may be desired. Into the body, over the pin a,is east or otherwise immovably attached a staple, b, of such size thatthe said pin can be withdrawn from the hole in the plug but not from thehole in the body, and when a padlock is fastened in said staple the pincannot be withdrawn from the plug. By this means the plug can be lockedeither open or shut, so that nobody but the proper person can change thesame.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the body A and plug B with holes, as described, thepin a, and the staple b, substantially as and forthe purposes herein setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

HENRY ESSEX.
